Using hot air to convey the material, the inlet air temperature is regulated based on the material's moisture content to dry material with input moisture as high as 15%, achieving output moisture < 1%.
It integrates crushing, grinding, drying, powder selection and transportation in one, with compact layout, can be arranged outdoors, and has low investment cost.
The material stays in the mill for a short time, making it easy to detect and control the product particle size and chemical composition, reducing repeated grinding and stabilizing product quality.
Small vibration, low noise, fully sealed system operating under negative pressure, preventing dust leakage, ensuring a clean environment and compliance with environmental protection standards.
The automatic control system enables remote operation, featuring thin oil lubrication system and hydraulic device, no need to disassemble for maintenance ensuring quick service and low maintenance costs.

The mineral falls onto the center of the grinding disc through the feeder outlet. When passing through the grinding roller area, it is crushed by the grinding roller. Large pieces are directly crushed, and fine particles are squeezed to form a material bed for inter- particle grinding.
The ground mineral is carried away by the strong airflow of the wind ring, while the larger mineral particles fall back to the grinding disc for further grinding. The powder in the airflow passes through the separator blades, and the coarse particles return to the grinding disc for grinding. The qualified fine powder is discharged from the mill along with the airflow and collected by the powder collector as final product.
Liming Heavy Industry, a total solution provider for grinding equipment, is a modern manufacturer of vertical roller mill, European type trapezium mill, micro powder mill, superfine vertical roller mill, sand powder vertical mill, etc. We provide grinding equipment and services from single units to full systems, and the professional technology covers the entire process chain of mineral processing.
